STANCHION.

' SPECIFICATION forming part of Letters Patent No. 456,871, dated July28, 1891.

To aZZ whom it may concern:

Be it known thatI, JOHN O. WIOKS, a citizen of the United States,residing at Truxton, in the county of Cortland and State of New York,haveinvented certain new and useful Improvements in a Self -Adj ustableCattle-Stanchions andI do hereby declare the following to be a full,clear, and exact de-- scription of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to a cattle-stanchion;

and the object of my invention is to provide a self-adjustable stanchionthat is, a stanchion that can be placed in the position required for theinsertion of the animals head, and when so inserted it closes itself.Iattain said object by a certain construction and arrangement of parts,fully described in this specification and illustrated in theaccompanying drawings, in which Figure 1 is a front view of thestanchion in a position to receive the animals head. Fig. 2 is a similarview, with parts broken away, illustrating the stanchion'when closed.

Referring to the drawings, the letterA designates the verticaloscillating bar, which has itslower end pivoted at b to the inner sideof the base-bar B of the stanchion. center of said bar there is pivotedthe treadle 0, having the reduced portion 0, which is adapted to adjustitself to the pin 61 and engage the same when the vertical oscillatingstanchion-bar A is placed in the position indicated in Fig. 1.

To the top of the vertical bar A there is secured a chain or cord E,which passes through an orifice in the top of the vertical stationarybar F, thence over the pulley G and downward into the cavity H. To thelower end of this cord E there is attached a weight I. It will beobserved that the pulley G revolves between the parallel bars J and hasbearings therein at j. Between the parallel bars J there is rigidlysecured the stop K, which stops the vertical sliding bar A in aperpendicular position, as shown in Fig. 2, when the stanchion isclosed. It will further be seen that the vertical sliding bar Aoscillates between the parallel bars J in the slot L,

and that said bar is rigidly secured in posi tion when closed by meansof the pivotal stay or treadle 0 below its pivotal point.

Near the Application filed December 30, 1890- Serial No. 376,283. (Nomodel.)

M, which is pivoted to the top of the vertical bar N.

D represents a small horizontal .bar, which is rigidly secured to thevertical stationary bar N slightly below the point at which thecentrally-pivotal latch or treadle O is pivoted to the oscillating bar Ain order that the projecting end of said bar D may strike the latch Oneend of the bar D projects slightly beyond the stationary bar N, and isprovided with a notch d, which fits intothe reduced portion 0 of thetreadle C. It will readily be observed that the centrally-pivoted latchC is set and thrown by coming in contact and co-operating with the smallbar or trip D. This is a novel,valuable, and practical feature of myinvention.

The operation of my stanchion is as follows: The same is placed in theposition shown in Fig. 1, with a view of receiving the animals head atthe opening 0. WVhen the head of the animal is inserted at O, the lowerportion of the neck comes in contact with the latch or treadle O, whichis thrown, and the, vertical sliding bar A assumes a perpendicularposition, as shown in Fig. 2, when the same is rigidly secured by thepivotal stay M, which securely holds the animal.

As it is apparent that my invention is very practical and useful for thepurpose designed, I deem it useless""to further enlarge upon its merits.

What I claim is- In a cattle-stanchion, the combination of the Verticaloscillating bar A, having itslower end pivoted to the'base of thestanchion, the latch 0, having the reduced portion a and centrallypivoted near the center of the bar A, a small horizontal bar D,providedwith the notch d and secured to the'vertical bar N, so as to strike thelatch 0 below its pivotal point, and the mechanisnrfor returning andrigidly securing the bar A in an upright position, substantially asdescribed, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
